let's say they pinkie pie was just a mean no fun bully like babs when she was a filly and that these three had to teach her how to have fun and be nice again! here's a version of the "babs seed" song from one bad apple

applejack: first we thought that pinkie was so really really fun a new friend in school and we thougth it could be done

*Pinkie enters with fluttershy and Twilight behind her*

rainbow dash: but then we found the truth she's just a jerk from a rock farm she went from joyful to a pony that could harm

Rairty: every where we turn. water balloons are hurled!

ALL: Bad Pie! Bad Pie! what we gonna do a jerky ponies are on tails we got to hide we got to bale!

ALL: Bad Pie! Bad Pie! If she's throws a cake at you. you gotta run before more comes and the you'll finally be done

ALL: bad pie bad pie. be better if we die!*

Applejack: this pinkie is a jerk and her main is very flat we really got to get away from her and those two brats!

Rainbow dash: i'm sure as long as we don't try to hang with her she'll leave us alone and never come no. no sir

Rarity: but of course even so. for now she'll play mean tricks

*REPEAT VERSE

Rainbow Dash: why so mean why no fun?

Rarity: she looks like she never went out in the sun

ALL: can't you just stop? can you just listen? we can teach fun just please stop this!

Shouldn't it be Rarity instead of Fluttershy? I mean it's REALLY AWESOME but it's like they're taking the CMC's places. AJ as Apple Bloom, Rainbow Dash as Scootaloo and Rarity as Sweetie Belle instead of Fluttershy. Just an opinion.
